简要总结

The primary study objective is to determine if microdoses of ABY-029 (up to 6X) lead to detectable signals (defined as signal-to-noise ratio, SNR ≥10, with wide-field iFI) in sampled tissues with an EGFR (epidermal growth factor receptor) pathology score ≥ 1 based on histological staining.

The secondary study objective is to assess ex vivo the specificity of tumor binding in resected specimens by measuring the corresponding molecular uptake and concentrations using histopathology.

详细描述

The investigators plan to enroll a minimum of 6 and a maximum of 12 adult patients with a diagnosis of operable head and neck cancer in this open label, single center, clinical trial of ABY-029.

Administration of ABY-029 will occur as a single intravenous injection to subjects with operable head and neck cancer approximately 1-3 hours prior to surgery.

Documentation of the tumor with digital photography will be performed at several time points during surgery: pre-resection, at intermediate time points during surgery, and post-resection. White light assessment of the tumor and boundaries will be performed by the surgeon.

Intraoperative optical probe measurements will occur in areas of visible tumor as well as normal appearing tissue. At multiple time points during each surgery and at the discretion of the surgeon, optical probe measurements will be completed with the probe followed by biopsy sampling of the same sites when they are intended for resection. Commonly, these acquisitions will occur at first exposure of the tumor, at the approximate mid-point of tumor resection (when a significant amount of tumor tissue is present in the operative field), at a point nearing but prior to completion of tumor resection (when a small amount of tumor tissue is presumably present), and at the intended completion of tumor resection (when residual tumor may or may not exist). At a data collection time point, optical probe measurements will be performed and archived for analysis and locations may be biopsied when tissue is intended for resection.

Any normal tissue removed as part of surgical procedure will be sampled. Samples may be taken from tissue outside the "antic" tumor volume but resected as part of the procedure along the surgical corridor. All tissue collected will be submitted to pathology for routine processing.

研究组 & 干预措施

ABY-029

Experimental

Between 3-9 patients will be administered ABY-029 as a single intravenous injection approximately 1-3 hours prior to surgery.

干预措施: ABY-029 (Drug)

结局指标

主要结局

Signal detection

时间窗: Day of surgery, up to 1 week after surgery

For each pathology, predictive models of the odds of tumor positivity for biopsies given concentration of ABY-029 will be constructed. Histologically confirmed tumor status from biopsies will be statistically analyzed against the predictive models. The quantitative fluorescence measures will also be assessed for their fit with statistics. The predictive accuracy of the model fit will be summarized through an index.

次要结局

  • Correlation of spatial patterns of EGFR expression(within 1 week of surgery)
